Cheapflights was founded in 1996 by John Hatt. [3] That year, its first website, www.cheapflights.co.uk, launched. [4] In 2000, ex-ABN Amro banker David Soskin and Hugo Burge led a buyout of the website from its founder.
In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg. The actual surface pressure will vary from this at different locations ...
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
6 February 1996 – Birgenair Flight 301 crashed into the sea shortly after takeoff due to incorrect readings from the airspeed indicator. The suspected cause was a blocked pitot tube (this was never confirmed, as the airplane wreck was not recovered). [9] 2 October 1996 – Aeroperú Flight 603 crashed because of blockage of the static ports ...
Diagram showing the face of the "three-pointer" sensitive aircraft altimeter displaying an altitude of 10,180 ft (3,100 m). Reference pressure of about 29.92 inHg (1013 hPa) is showing in the Kollsman window. An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.

[2] [3] In some very high-speed aircraft such as the Space Shuttle, equivalent airspeed is calculated instead of calibrated airspeed. Air data computers usually also have an input of total air temperature. This enables the computation of static air temperature and true airspeed.
TAS is used for flight planning. TAS increases as altitude increases, as air density decreases. TAS may be determined via a flight computer, such as the E6B. Some ASIs have a TAS ring. Alternatively, a rule of thumb is to add 2 percent to the CAS for every 1,000 ft (300 m) of altitude gained. [1]: 8–8, 8–9
TERCOM systems receive constant fixes during the flight, and thus do not have any drift. Their absolute accuracy, however, is based on the accuracy of the radar mapping information, which is typically in the range of meters, and the ability of the processor to compare the altimeter data to the map quickly enough as the resolution increases.
